【Continuously invaded by strong sounds…Engthodontic membrane strength +1, external auditory canal strength +1】

【Continuously attacked by strong voice…】

As the strength of the eardrum increased, Chen Mu immediately felt the harsh music soften.

He was overjoyed and it was indeed useful.

Continue to increase the volume.

90 decibels - The music that just felt soft became very harsh immediately.

But the next second, the transplanted flowers and wood followed.

【Due to continuous invasion of strong sound, damage transfer -50,-50,-50,-50...Tympanic membrane strength +2, external auditory canal strength +2, hearing +2】

【Continuously attacked by strong voices... Listening +1, +1, +1】

“…”

Chen Mu continued to increase the volume.

110 decibels.

This decibel is enough to pierce the eardrum of a normal person.

But Chen Mu only heard a sound like a blackboard scratching the blackboard, sharp and harsh.

The next second, the sound disappeared.

【Damage power transfer-80,-80,-80,-80…Engthumblast strength +3, external auditory canal strength +3, hearing +3…】

Chen Mu was so excited that he wanted this feeling.

He adjusted to the highest level - 140 decibels!

【Damage transfer-140,-140,-140,-140…Enemoji strength +6, hearing strength +6…】

Before he could be happy this time, a few glass cups on the table diagonally opposite and a row of glass frames on the wall were all broken.

The screen of the decibel measuring instrument placed next to it flashed, and bursts of black smoke also emanated from it.

"not good!"

Chen Mu turned off the speaker immediately.

"Pu--"

The glass on the wall still fell down, and the ground was in a mess!

At this moment, he heard the soundproof room being knocked "bang bang" from outside.

Chen Mu opened the door and found that there were many people watching the fun outside.

The boss squeezed in and said angrily: "You're so desperate, the sound is so loud? My soundproof room is just for soundproofing, and the maximum soundproofing is only 100 decibels."

Chen Mu laughed and said, "Don't be angry, don't be angry... Don't worry, I will compensate you according to the price if you break it."

"Is something wrong? Is it a compensation problem?" The boss looked at the ground and roared in anger. "These large frames are 300 yuan per, and the sound measuring equipment is 580."

"Okay, I'll compensate according to the price!" Chen Mu said with a smile, "Please help me calculate how much the soundproof room and the audio cost in total?"

When the boss heard this, he suddenly changed his face like a Sichuan opera. He was furious the previous second, and immediately asked, "How many square meters?"

Chen Mu thought for a while and said, "It's about 30 square meters."
